Featuring a welterweight title fight between Nick Diaz and Marius Zaromskis, “Strikeforce: Miami” takes place Jan. 30 at the BankAtlantic Center in Sunrise, Fla., and airs on Showtime.

MMAjunkie.com first reported the likelihood of the Hieron vs. Riggs fight last month, and we confirmed on Tuesday that the organization was also targeting Lawler vs. Manhoef for the card.

Lawler was expected to fight this past December at “Strikeforce: Evolution,” but opponent Trevor Prangley was a late scratch from the card, and the fight was pulled from the event. The final EliteXC middleweight champ, Lawler seeks to bounce back from a June loss, held at a catchweight of 182 pounds, to current Strikeforce middleweight champ Jake Shields. Prior to the loss, the UFC, PRIDE and IFL vet was on a five-fight win streak, and all five wins had come by knockout or TKO.

Manhoef, who signed with Strikeforce last month, is also a K-1 kickboxer (37-8) who’s previously competed for MMA organizations such as Cage Rage and DREAM. After a recent win over Kazuo Misaki, the Dutch fighter is now 7-2 in his past nine fights, and the losses came to notables Gegard Mousasi and Paulo Filho.

All of Manhoef’s past 15 MMA victories have come via knockout. In fact, he’s claimed 23 of his 24 career MMA wins by TKO or KO.

Hieron, of course, was slated to fight Diaz for Strikeforce’s first-ever welterweight title in August. Diaz, though, wasn’t licensed for the fight (after skipping a mandatory drug test), and Hieron instead earned a unanimous-decision victory over replacement Jesse Taylor. It was his sixth consecutive victory.

Riggs also brings some name recognition to the card. The former top UFC welterweight contender defeated Luke Stewart in November 2008 but broke his hand in the fight and was sidelined for seven months. He’s since defeated Phil Baroni via decision at this past June’s Strikeforce event, and he earned a pair of quick victories in December in smaller promotions.

Riggs has now won four straight fights and is 7-2 since July 2007.

With the official additions to the card, “Strikeforce: Miami” now includes:

A total of 26 fighters got their chance to shine on Saturday as part of UFC 190 at Rio de Janeiro’s HSBC Arena. Now that UFC 190 is in the books, it’s time to commence MMAjunkie’s “Three Stars” ceremony.

The man known for cranking submissions to the point of injury added eye-gouging to his repertoire. But is the controversy of Rousimar Palhares too essential to his bizarre, awful appeal for his employers to take any meaningful action against him?
